AREAS AFFECTED...SERN MO/SRN IL/SWRN INDIANA/WRN KY/WRN TN/NERN
AR/NRN MS

CONCERNING...SEVERE POTENTIAL...TORNADO WATCH LIKELY

VALID 260838Z - 261045Z

SLOWLY INCREASING SEVERE POTENTIAL ACROSS THE MID MS/LOWER OH VALLEY
REGION WILL LIKELY REQUIRE NEW TORNADO WATCH IN THE NEXT HOUR OR SO.

LOW-LEVEL MOISTENING CONTINUES ACROSS THE DISCUSSION AREA THIS
MORNING AS SURFACE SLYS CONTINUE TO INCREASE AHEAD OF THE
APPROACHING UPPER SYSTEM AND ASSOCIATED COLD FRONT.  STORMS LIKEWISE
HAVE CONTINUED TO INCREASE/EXPAND SWD ALONG THE FRONT INTO NRN/WRN
AR...AND EXPECT FURTHER CONVECTIVE INTENSIFICATION AS LOW-LEVEL
MOISTENING/WEAK DESTABILIZATION CONTINUES.

ALONG WITH THE INCREASING MOISTURE/INSTABILITY ON STRENGTHENING
LOW-LEVEL SLYS...STRONGER MID-LEVEL SWLYS CONTINUE TO SPREAD EWD
ACROSS THE DISCUSSION AREA AS THE POTENT UPPER SYSTEM PROGRESSES
ACROSS THE MIDDLE AND LOWER MO VALLEYS.  THE RESULTANT STRENGTHENING
OF THE VERTICAL SHEAR PROFILES WITH TIME WILL SUPPORT A STEADILY
INCREASING RISK FOR DAMAGING WINDS AND TORNADOES THROUGH THIS
MORNING.
